Re: WARNING: Lithium Batteries

You could if you added two resistor (one for each slot) on the empty pads by the ADC. This would create a voltage divider to monitor the higher voltages. Even so, you would still need to do a lot of programing and over all I just don't suggest playing with lithium chemistries on this charger.

Re: Optical Isolation on USB Port

I am working on a little optoisolator board to go between an FTDI adapter and the charger. That way for those who are interested in monitoring real time with their computer (not just programing the charger) can do so.

Re: Full Cycling data

Yeah, I was trying to troubleshoot the voltage sag problem when I realized it's our house power!! We have been dealing with it for two weeks now (lots of frustrating phone calls). Nothing against electricians, but I get frustrated when they talk down to me. It's not like I don't know anything about ...

Re: NFC Support

I like it! So we just make a spot on the outside of the charger where scanning happens. You power it up with no batteries, then scan a cell and put it in a slot. The scan and that slot are tied together and you repeat for each battery. Hit a button when you are done loading however many you are goin...

Re: Full Cycling data

I cycled two older Raovacs that I know are not the best... but they work well enough in low drain devices. Anyways, I noticed the estimated internal resistance number varies quite a bit between cycles. So one of the cells will charge fine sometimes, and other times I get the purple. I am trying to t...

Re: Discussion of Mark's firmware

Mark, I think you should drop the white light during charging. Not that I don't think it is cool, I just think we should try and keep the colors more tied to function; white waiting for button, red charging and so on.

Re: Full Cycling data

Attached is a bunch of cycle data from 0.514 (I could not upload it all because it said "the board attachment quota has been reached") Mark, I think I had asked this before but is it possible to have the battery numbers be 1 and 2 instead of 0 and 1? I think you had said it was more trouble than it ...

Re: NFC Support

Yes, bar code would work in a dream charger... Probably not in this one, but we will see.

Re: Independent Charging Channels

For maximum charging rates, you then either use the side channels together, or the top and bottom channel together.
Exactly!
